The object pf this invention is to provide an improved closure particularly or use with containers made of paper or like material and havingan outwardly projecting 5- bead formed around them near their upper vedge. A

The present invention isillustrated in the accompanying drawing, which in .Figa 1 showson an enlarged scale the improved l0 closure as it' is being applied to a container, while in Fig. 2 such closure is shown in its final position.

may bev of paperl or like material, is formed near its upper edge with an outwardly extending bead or projection B. The extent of projection of the bead B from the con-v tainer is not important and may vary considerably, as, as will be hereinafter described, the fit of the closure does not depend thereon. Such closure consists as shown of a disc C of metal or other suitable material, such as wood fibre, with a depending flange D wardly projectlng bead The internal diameter o f the closure at the lower edge F of bead E is less than the greatest'external diameter'of the bead B on container A, so that the closure has to compress such bead I 3o `B when it is being applied to the container,

as in the position shown in Fig. 1, where it will be seen that owing to the rigidity of the material-of which the closure is composed, Aand the elasticity of the material vof the container, the bead B on the latter has been pushed inwardly to lallow the edge- F of1 bead E of the closure to pass.

Below the bead E-the lower edge ofthe closure is openedoutwardly, as shown at G, theobject of thisbeing to facilitate the application of the closure by idingit over Y `the container bead 'BL IThis' construction also facilitates the use ofh suitable tool to assist if necessary in the removal of thel closure when re uired. j A

v The lower e ge of the opened out rtion G of the closureis preferablyv rolleup outwardly as at Hto give a smooth edge to the' closine -andjalso to strengthen-and stifenthe wdattenf- Y 1 n, ticity of the bead B against the -ri 'It will b e seen v`that the container A, which around its edge, such fiang havmganoutit has to be forced past the point immediately The operation of the improved closure will v be readlly understood from the above de-` scription, but it may be pointed out that the beads B and E are not in the same relative planewhen the closure is in position, and that the sealing of the container .is eifected between the point I at the extreme upper edge of the container and the point on the bead B thereon with Jwhich the edge F of bead E of the closure comes in contact, the closure being 00 pulled down tightly onto edge I b `the elasd edge F. It will be seen that this construction permits of a good-closurev beingobtained even with 'any possible variation in the extreme 05 outer diameter of bead B due to moisture and variation in the material of which the `conrtainer is composed.

Ifdesired a aper dscJ may be placed in ythe closure as own, so that the contents of .7 the container will not be able to come into contact with the material of which the closure isu formed. In order .to'prevent the disc J from falling out of the closure when the latter 'is rembved from the container, it is preferred 75 to taper the upper portion of flange D slightly outwardly from bead E to the topas shown, and to make the paper disc of suchl a size that above the bead E- What I claim and ters Patent is A closure for use with a container having an outwardly projecting befad formed near its upper end, the closure comprising a disc having a depending ange formed with an 8 desire to secure by Let- Voutwardly projecting bead the llowerinside edge of which is adapted to compress the bead -on the container in passing over same and to enga ewith the lowerfsurface of such bead, and t e `ortion of the closure below the bead thereonl ing oplened outwardly to facilitate thepassing of t Ve inner edge of the bead on the closure over the bead on the container, the width of the concave finner side of the bead ofthe closure'ibein 'greater than that of the e bead of the container,
